Estimate Equity
Drag the slider to your best guess of Player 1's equity, then lock it in. Get within five points to keep your streak — trains real feel, not just buckets.
How to play

Slide your guess. Set the slider to Player 1's equity.
Lock in. Within five points of the truth is a hit.
Equity shapes to memorise (favourite's %)
Each round shows two pre-flop hands. Move the slider to the equity you think Player 1 has, then press Lock in. The reveal shows the true equity and how far off you were. Within five points is a hit and grows your streak.
Anchors for a good estimate
Don't guess from scratch — adjust from the nearest known shape. A coin flip (pair vs two overcards) sits near 55/45. A dominated hand — same top card, worse kicker — is around 70/30. Two big cards versus a smaller pair is a near race, about 46/54. Overpair versus underpair is roughly 80/20. Slide from whichever anchor is closest and you'll rarely be far off.
Why exact estimates matter
Bucket knowledge ("about a flip") gets you started, but close estimates let you make thin calls and folds confidently against your pot odds. Want the precise figure for study? Open the equity calculator. Prefer multiple choice? Run an Equity Sprint.
Frequently asked questions
What is Estimate Equity?
A free drill where you're shown two pre-flop hands and set a slider to your best guess of the first hand's equity. Lock it in and see how close you were to the true number. Land within five points and it counts as a hit.
How close do I need to be?
Within five percentage points of the true equity counts as correct and extends your streak. Five points is tight enough to prove you really know the match-up, loose enough that a good estimate scores.
How is the true equity worked out?
When you lock in your guess, the match-up is run through a Monte-Carlo simulation of thousands of random boards in your browser — accurate to well under a percent.
How do I get better at estimating?
Anchor to the standard shapes: a pair versus two overcards is about 55/45, a dominated ace is around 70/30, and a big-card hand versus a smaller pair is a near race at roughly 46/54. Adjust from the nearest anchor.
